Load Frequency Control Based on Equivalent-input-disturbance Method for Isolated Small Hybrid Power System
In any isolated small power system employing a mix of renewable energy (RE) technology and legacy technology, frequency deviation is inevitable due to RE fluctuations and load demand variations. Therefore, an appropriate frequency control scheme is essential. This paper presents an Equivalent-Input-Disturbance (EID) control for load frequency control of isolated small hybrid renewable energy power system. EID method is applied to regulate the output power of the diesel generator and electric vehicle (EV) to maintain the power balance and ultimately maintain the frequency within normal range. Simulation studies show that this strategy has higher flexibility and control performance than the traditional PI method.
